EDWARD WALnRoN,

, .WALDRQN, FLEXIBLE or PHILADELPHIA, PENNSYLVANIA, ASSIGNOR r ROTARY ENGINE COMPANY, or CAMDEN, NEW

. ERsEY, A CORPORATION OF NEW, JERSEY. a -.CDUPLINGiL Be it'nknown that I,

residing at Philadelphia, in the -county of one from the other wit at an angle to each other or paralle rela- "end holes 5 therethrough. Th

.right angles to that of the Philadelphia andyState of Pennsylvania, have invented certain Improvements -1n' Couplings, of which the following is a specication;

This invention is a flexible coupling suitable for connecting shafts used in transmitting power, sojthat they may revolve together when out of alinement; and its leadprovide in such mechan'' mg purpose is to ism flexibility combined with simplicity, strength, durability, and self-lubrication.

In the accompanying'drawings,Figure 1 represents a longitudinal sectional view of a couplin made in accordance with theinvention. ig. 2 represents a side elevation of parts thereof, and Fig.3 represents a plan view of the center piece.

e mechanism comprises a pa1r of similar ieces each having an-internally-threaded sl eve 1, with a circular flange or disk 2 thereon, with curved central sockets 3 therein, and thereon cylindrical lugs 4', with e end pieces have disposedbetween them a center piece comprising a body portion in the form of a ring 6 with curved hubs Tprojecting from the faces thereof and having the holes 8 therethrou h and'with bylindrical bearings 9 formed in t e ,oppositepfaces of the ring, the sockets. 3 receiving the hubs therein. p

The holes 8 and bearings 9 of each face of the center piece have a common axis disposed at right angles to that of the other; The lugs 4 of each end iece fit and revolve in bearings 9 of a face of the center-piece ring, and pins 10 are set in the holes 5 and pass freely through the holes 8 to engage the end pieces to the center-piece; Thus each sleeve is provided with an oscillating andlaterallymovable connection to the center piece at other, sufficient space being provided between the disks 2 and ring 6 and between the sockets 3 and hubs 7 to secure suchfre edom of movement, and hence shafts connected to the sleeves may rotate to ether and be driven i1 their lines dis osed I Specification of Letters Patent.-- Application filed -l'unc 24,1906.- Serial K0. 286,715.

' is normally closed by chamberis filled with a lubricant which works along the pins 10, passing through the chamling from one shaft .degrees to permit the parts to be joine 7, which have free play versely to each other andsaid end respective Patented July ,2}, .1906.

a i The center-piece has therein a chamber 11, EDWARD W ALDRON,

withits ends closed by disks 2, the chamber being filled with oil through a duct 13; which: a.screwp.1ug 14 This ber, through the holes 8, and into the bearings 9, thus lubricating all the movable parts.

The construction will be seen tobe such that power is transmitted through thecouping or-straining the pins, the lugs of the end pieces, and the bearings of the center piece taking the torque; The cylindrical bearings 9 are full semlcylinders terminating in tan are extended beyond one'hundred and ei ty gent planes 9 and the surfaces of the llis 4- to the other withoutwear gether, so that a fair engagement takes place between them in transmitting motion of ro-,

tation while permitting freedom of oscillation As the transversely-disposedpins. 10

move freely in t e holes 8 and as thehubs 7 have free play in derstood that the respective 'end pieces 1 are connected to the extending transversely to each other and reciprocate in planesv transverse to their re,-

spective planes of oscillation. Having described my invention, I claim- 1. A coupling comprising a pair of'similar end pieces each having a socket therein and curved lugs thereon, an intermediate piece havinghubs res -"ectively dis osed in said sockets and angu arly-dispose curved bearings inwhich said lu s are engaged, and ins respectively passing t ough a hub of sai intermediate piece and lugs of one of said end pieces,

2. 1! coupling comprising end members and an intermediate mem.ber,'said intermediate member, having oppositeli-disposed curved bearings with axes exten 'ng transmembers having curved bearings en corresponding bearings of t e intermediate member, and angular'ly-disposed pins passing through and engaging said end and intermediate members.

-3. A coupling comprising an intermediate ember having curved bearings on each of two parallel sides thereof, the axes of said the sockets 3, it will be un intermediate member-'6, sothat the end members oscillate upon axes aging iWith the 4 ing transversely to each other end members bearings lying in parallel planes and extendh'avingcurved bearings adapted to engage and oscillate in relation to the bearings of said intermediate member, and pins in the axesof oscillation of said bearings engaging said endand intermediate members together.

4. A coupling comprising end pieces having T recesses therein and lugs with curved bearings thereon, a center piece having projec tions disposed in said recesses and concave bearings angularly disposed for engaging said lugs, and pins passing through said lugs and projections for securing said members together. i

5. A coupling comprising a center piece com risin arin havin curved bcarin s an oil-chamber in said bearing-piece, end pieces throug I having curved bearings engaging the bearings of sai center piece, and pins connecting said center iece to said end pieces and extending li'said oil-chamber, said oil-chamber communicating with the Q bearings of said i parts,

I 6. A coupling comprising a pair of sleeves each having a recess and curved bearings, an

intermediate member having projections said recesses and curved bearings withtransverse axes which fit the bearings of said end members, and transversely-extending pins adapted to oscillate and move laterally in v respectively passing throughthe bearings of an end member and a projection 'of the intermediate member, said end members oscillating on and reciprocating in the direction of p the axes of said pins.

In testimonywhereof I have hereunto set my hand, this 23d day of June, 1905, in the presence of the subscribing witnesses.
